Antarctica is roughly 5.4 million square miles (14 million square kilometers) in size, and that's with all of its ice. There is a land mass beneath, which looks like this. Twitter user Icebridge made this image to illustrate just how large our most unvisited continent actually is.

Conversely, "it is estimated that at any given time there are (only) 1,000 people 'living' in Antarctica, but this varies depending on the season." (from Answerbag.)

IceBridge is part of NASA's current enormous endeavor to make flight paths over Antarctica to determine ice thickness, among other things, in light of the previous method of relying on NASA's ICEsat satellite, which is dying. The crew, including a group of students and engineers from Lawrence, KS (Center for Remote Sensing of Ice Sheets) is based in Puntas Arenas, Chile, and make 11-hour flights down to Antarctica and back on an almost daily basis.
